Welcome aboard. I see from your pictures that your gun is stamped Grade
2 above the serial number and Quality
E below on the watertable. My heavy, a bit over nine pounds, 12-gauge 56213 is similarly stamped,
2 above and
E below the serial number.

One would normally expect a Grade
2 to be stamped
G below the serial number if it is a 12-gauge or smaller. The
E normally indicated a 10-gauge which cost $5 more.
